Key Parameters

Substitute Part Grouping Explanation

Substitution of the IL 612A-2 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Isolation voltage: 2500Vrms
• Number of channels: 2
• Channel configuration: Unidirectional, 1 input per side
• Data rate: 10Mbps
• Common mode transient immunity: 15kV/µs minimum
• Package type: 8-DIP (0.300", 7.62mm)
• Mounting type: Through Hole
• Supply voltage range: 3V ~ 5.5V
• Technology: GMR (Giant Magnetoresistive)
• Series: IsoLoop®

The IL 612A-2E qualifies as a direct substitute based on complete alignment with all mandatory parameters. Differences in product status, operating temperature range, and compliance certifications do not affect functional substitutability for the specified electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

IL 612A-2E as Primary Substitute:

The IL 612A-2E is the direct functional equivalent of the IL 612A-2. Both components share identical electrical specifications across isolation voltage, channel configuration, data rate, common mode transient immunity, supply voltage, and propagation delay characteristics. The 8-DIP through-hole package is identical, ensuring direct PCB compatibility without layout modifications.

Product Status Consideration:

The IL 612A-2 carries obsolete product status, indicating discontinued manufacturing and limited long-term availability. The IL 612A-2E maintains active product status from NVE Corp/Isolation Products, ensuring ongoing supply chain access and manufacturer support.

Compliance and Certification:

The IL 612A-2E achieves ROHS3 compliance, meeting current regulatory requirements for electronic components in regulated markets. The IL 612A-2 is RoHS non-compliant. For applications subject to RoHS directives or customer compliance requirements, the IL 612A-2E is the appropriate selection.

Operating Temperature Range:

The IL 612A-2 operates across -55°C to 125°C. The IL 612A-2E operates across -40°C to 85°C. Applications requiring operation below -40°C or above 85°C must retain the IL 612A-2 or identify alternative isolators with extended temperature specifications. For standard industrial and commercial temperature ranges, the IL 612A-2E is suitable.

Frequently Asked Questions (FAQ)

Q: Can IL 612A-2E directly replace IL 612A-2 in existing designs?

A: Yes. The IL 612A-2E provides identical electrical performance and physical package compatibility. No circuit modifications or PCB redesign is required. Direct pin-for-pin substitution is supported.

Q: What are the key differences between IL 612A-2 and IL 612A-2E?

A: The primary differences are product status (obsolete vs. active), operating temperature range (-55°C to 125°C vs. -40°C to 85°C), RoHS compliance status (non-compliant vs. ROHS3 compliant), and packaging format (unspecified vs. Tube). All electrical and mechanical specifications are identical.

Q: Are there any thermal or performance implications when switching from IL 612A-2 to IL 612A-2E?

A: No thermal or performance implications exist within the overlapping operating temperature range of -40°C to 85°C. Both components use identical GMR technology and deliver identical propagation delay and common mode transient immunity specifications.

Q: Does the IL 612A-2E packaging format affect compatibility?

A: No. The IL 612A-2E is supplied in Tube packaging, which is a standard distribution format for through-hole components. The physical component dimensions and pin configuration remain unchanged. Tube packaging does not affect PCB assembly or electrical performance.

Q: What should be considered if the application requires operation below -40°C or above 85°C?

A: The IL 612A-2E operating temperature range is -40°C to 85°C. Applications requiring extended temperature operation below -40°C or above 85°C must retain the IL 612A-2 or identify alternative digital isolators with extended temperature specifications from the manufacturer.

Q: Is the IL 612A-2E suitable for new designs?

A: Yes. The IL 612A-2E is the active product offering from NVE Corp/Isolation Products. New designs should specify IL 612A-2E to ensure long-term supply chain support, manufacturer technical support, and compliance with current regulatory standards.

Q: How does RoHS compliance affect component selection?

A: RoHS compliance is a regulatory requirement in many markets. The IL 612A-2E achieves ROHS3 compliance, meeting current standards. The IL 612A-2 is non-compliant. For applications subject to RoHS directives or customer compliance mandates, IL 612A-2E is the required selection.
